2004 Khobar massacre

The 2004 Khobar massacre occurred from 29-30 May 2004, when four al-Qaeda in the Arabian Peninsula gunmen (Fawaz al-Nashimi, Nimr al-Baqmi, Husayn, and Nadir) attacked two oil installations and a residential compound in al-Khobar, Saudi Arabia, killing 22 and injuring 25. The attackers attacked the Arab Petroleum Investments Corporation Building, the al-Khobar Petroleum Center, and the Oasis Compound in the attack, targeting foreigners. An American and two Filipinos were killed at the Petroleum Center by four terrorists at 6:45 AM, and terrorists proceeded to attack the Apicorp building, using an RPG-7 to kill two security guards at the gatehouse, killing a 10-year-old Egyptian boy who was the son of an employee, and killing a British man and a Saudi man at the nearby intersection. Police killed the terrorists before they could make their escape.

At 7:30 AM, six terrorists scaled the walls of the Oasis 3 Compound, and five drove up to the vehicle checkpoint. The cars were let through, and the terrorists opened fire on security guards and a school bus. The terrorists then entered the residential complex and slit the throats of non-Muslims, eating breakfast in the restaurant the next morning and killing eight Hindu Indian employees. Four terrorists managed to escape the Soha Towers Hotel in a stolen car, booby-trapping the hotel to deceive Saudi soldiers; they proceeded to flee. The other terrorists were attacked by Saudi helicopters at the hotel, with two being killed and one being captured; most of the terrorists had fled before the Saudi raid. The surviving four killed a security guard and injured eleven military personnel in Downtown Khobar, and the terrorists managed to escape. The attack was a morale boost for al-Qaeda, and oil prices soared to $42 a barrel after the attack. In 2016, some of the terrorists involved in the attack were executed. Abdel Aziz al-Muqrin, the mastermind of the attack, was killed in 2004, while Nashimi was killed that same year.
